CVE-2025-47356

Local memory corruption via concurrent double free

Published Jan 6, 2026 · Updated Jan 6, 2026

Double free in the Qualcomm Snapdragon Video component allows local users with low privileges to corrupt memory during concurrent access. Qualcomm has not published the affected function or shared resource, but the documented race allows multiple threads to free the same allocation. The local trigger requires low privileges and no user interaction; successful exploitation can read or alter protected data or interrupt the affected device.
